An archival historian of Cold War military affairs
Citing the archives, Ritter argued that Hungary's Southern Defence System was built not to invade Tito's Yugoslavia but to repel a Western attack expected through its territory.
László Ritter is a Hungarian modern historian whose research centers on intelligence, state security, the armed forces, and Hungarian-Yugoslav relations. In his study of the Tito-Stalin split, he reexamined Béla Király's memoir-based claim that the Soviet bloc prepared to invade Yugoslavia, using declassified Hungarian and international archival materials. By distinguishing Hungary's southern defenses and general-war preparations from an offensive plan, Ritter kept the question of Stalin's military intentions open while challenging an influential narrative.

The 'Secret War' between the Soviet Bloc and Tito's Yugoslavia
One of the distinct strands of Ritter's work is the intelligence war fought between the Soviet bloc and Tito's Yugoslavia. He writes that between 1948 and 1953 a secret war was waged between Hungary and Yugoslavia, in which the intelligence services of the two countries clashed. In his account this conflict forms a separate chapter in Cold War history because the state security organs of two equally Stalinist systems were competing with each other. On the Hungarian side three agencies handled intelligence (two belonging to the ÁVH and one military), whereas the rival had a single centralized organization, and Soviet advisers worked with the Hungarians. According to Ritter this was disadvantageous in two respects: Budapest forwarded everything of substance to Moscow while the Soviet organs told the Hungarians nothing, and the Hungarians inherited the conflict between Soviet military and state-security intelligence, which degraded the efficiency of their work.
The first operations look almost childish in retrospect but counted as real blows at the time. The two sides began by illegally distributing propaganda to discredit each other: the Hungarians mailed the Soviet party leadership's break letter to Tito to some two thousand Yugoslav trade-union leaders, and at the Vienna international fair in May 1950 ÁVH agents managed to swap the Yugoslav official information booklet for one containing the Moscow accusations against the Belgrade leadership. Ritter's archival research showed that the mutual accusations of abductions and assassinations appearing in diplomatic notes and the press were, surprisingly, mostly not the inventions of either side's propaganda but events that had actually occurred.
The most spectacular case was when a three-man group of Yugoslav intelligence (UDB) agents crossed the border illegally and abducted Dusán Vidovics, a high-ranking leader of the anti-Tito Yugoslav emigration. They lured him into a trap using forged ÁVH papers and then carried him off to Yugoslavia. The ÁVH then took seven other anti-Tito leaders into custody over Vidovics's disappearance without a trace, and in August 1952 it caught the group sent once more to abduct the emigration's leading figure, Boris Verstovsek. As Ritter recounts, almost nine thousand personnel of the organs hunted them for ten days, and the affair remained one of the ÁVH's most conspicuous failures.
Ritter regards it as difficult to determine the victims of the secret war precisely. He himself speaks in one place of 'more than a hundred fatal victims' and in another of 'several hundred,' which exposes that uncertainty. Only one assassination has been documented: a UDB agent from Murska Sobota shot an ÁVH informant who had recognized him. If one counts not only the dead as victims, then the indirect and direct casualties of the confrontation could have run to hundreds of thousands. For Ritter the greatest losers of the intelligence war were often the agents themselves, recruited from settlements along the border, and the national minority communities on both sides, Yugoslav Hungarians and Hungarians' Serbs and Croats, were obvious victims. Paranoid measures confined the life of the frontier population to unbearable limits (300,000 then lived in the zone on the Hungarian side), and on both sides thousands were interned or imprisoned as 'Titoists' and 'Cominformists' because of their views and origins or on fabricated charges.
This subject connects to his lasting research fields. His stated research areas include intelligence and state security in Hungary from 1920 to 1990, the Hungarian armed forces and military policy over the same period, and Hungarian-Yugoslav relations from 1945 to 1991. He presented the secret war between the Soviet bloc and Tito's Yugoslavia, 1948-1954, at a number of international scholarly conferences, and his Hungarian-language article 'Secret War between Hungary and Yugoslavia: Yugoslav and Hungarian Intelligence, 1948-1953' appeared in História 2010/1-2.
